semantique.ArrayProxy.reduce

ArrayProxy.reduce(reducer, dimension=None, **kwargs)

Reduce the dimensionality of an array.

Reduces dimensionality by applying a reducer function that returns a single value for each column along a given dimension, e.g. a summary statistic or a boolean.

See here for an overview of the built-in reducer functions that can be chosen from (they should be referred to by their name, without the underscore at the end).

Parameters:

• reducer (str) – Name of the reducer function to be applied.

• dimension (str) – Name of the dimension to apply the reduction function to. If None, all dimensions are reduced.

• **kwargs – Additional keyword arguments passed on to Array.reduce.

Returns:

ArrayProxy
